Newly released tests show high levels of lead in the drinking water of three subdivisions near Rock Hill.
South Carolina Water Service released the tests Monday from the River Hills and Foxwood communities in York County as well as Cedarwood in Lexington County.
The amount of lead, found in January, was up to four times above the federal standard.
Follow-up tests since Jan. 27 show that lead levels have fallen to within safe limits. Carolina Water Service was required to notify homeowners of its original findings and begin testing more frequently to make sure there are no more problems.
